Alguien me podria explicar cómo hago [tex] \ frac{3x - 1}{x + 2} - \ frac{2x}{x - 2} = \ frac{1}{{x} ^ {2} - 4 } + 3 [ / tex] Por favor que no entiendo nada.

Seria asi : 5 x 8 / 6 5 / 1 x 8 / 6 De ahi entonces multiplicas 1 x 6 (el denominador te va a dar 6), y multiplicas el 5 x 8, en total te daria 40 / 6 (simplificado es 20 / 3).
Respuesta : no tiene raiz exactapero simplificada es 2 raiz de 2.
